Guest fails detecting USB device

satimis · 09-16-2014, 09:58 PM

Hi all,

host Ubuntu 12.04 64bit
guest Win7
Oracle VirtualBox
Epson Perfection 3490 photo scanner
guest-addition on Win7 already installed on Win7

I have encountered the problem making Win7 to detect the scanner and tried several days without a solution. I found;
VirtualBox doesn't recognize USB [duplicate]
http://askubuntu.com/questions/14008...-recognize-usb

According to #22
I have installed gnome-system-tools on the host

$ groups satimis

Code:

satimis : satimis adm cdrom dip plugdev scanner lpadmin sambashare

Please help. Thanks in advance.

Regards
satimis

Did you try enabling the USB controller in the Virtualbox guest image?? Until you turn it on, it won't work. Right-click the image, click USB, and enable it. And the first two hits in Google for "USB devices won't work in virtualbox" are:
https://forums.virtualbox.org/viewtopic.php?f=3&t=22107
https://www.virtualbox.org/ticket/8873

...and one of which is a known bug report for certain USB devices.

Hi,

Thanks for your advice.

Yes, I have done.

Pls see USB Filter Detail.

I think it is NOT ONLY the problem of Win 7. Ubuntu 14.04 VM also has this problem unable to connect USB port

sudo fdisk -l

And again, as you've been told SEVERAL times before, spell out your words, and don't use text-speak. It's "please" not "pls".

Then does the scanner work/get recognized at ALL under the host OS, bypassing the VM totally??? Have you verified that the scanner/USB port/hub/cable are all working and good? This points back to a common issue somewhere...either hardware, or the Virtualbox additional tools aren't installed/working correctly, or USB is disabled. Two different OS'es shouldn't have the EXACT same problem, unless there is a commonality between them somewhere.

sudo fdisk -l

And what does your disk partition scheme have to do with a USB scanner?

I can scan under host OS

Previously "simple-scan" and "xsane" only worked as root. Then I fixed the problem. I could scan as user. But after running several

Code:

apt-get update ; apt-get upgrade

That problem comes back. Now I must run

Code:

sudo simple-scan/xsane

first. Then after exiting it I can scan as users. I haven't found what is the cause?

Edit-1
====
Remark:

Code:

HDDs
SSD 120G		OS
HDD1 (WD 2TB)		for VMs and data storage
HDD2 (WD 1TB)		for data storage (spare)

Edit-2
======
I found out the cause.

After booting, run "Home Folder"
To connect HDD1 it popup "request for password"
After login I can start xsane/simple-scane on host as user without going through as "root" first.

But on VM (Ubuntu 14.04)(even as root) or Win7 (even as administrator) still unable to find the device (scanner)

That's a separate issue.

And AGAIN...WHY does your disk partition have ANYTHING TO DO with a USB scanner??? What's the purpose of posting it?

Great...which isn't the question you posted in this thread.

...which takes us back to the VERY FIRST REPLY, and the one after that. AGAIN...either the virtualbox guest/additional tools aren't loaded, or you don't have the USB ports enabled on that VB container.
